May 23 (UPI) -- The U.S. Army Old Guard placed American flags on more than 228,000 graves at Arlington National Cemetery on Thursday as part of the annual "Flags In" tradition ahead of Memorial Day.
Some 1,000 members of the 3rd U.S. Infantry Regiment began placing the flags at each grave site and at the bottom of some 7,000 niche rows at the cemetery's Columbarium Courts and Niche Wall.
